ATTACHMENT FOR HARNESS-TRACES.

Specification of Letters Patent.

Patented June 29, 1909.

Application filed. September 12, 1908. Serial No. 452,711.

To all whom it may concern:

Be it known that i, th s'riiv Gonnnicn, a subject of the (lei-man lhnperor, residing at Domslau, Silesia, in Germany, have invented certain new and useful Improvements in Attarhments t r llarnes: 'l'raees, of which the following is a sperilication.

This invention ronsi J able eoupling for the attachment of harness trares to the ends of the. whillle tree or equivalent part ot the vehicle to which traces are intended to be secured.

in the annexed drawing liigure l a plan of the coupling, Fig. 2 a side elevation in open position and Fig. 3 a side elevation in olosed position.-

The coupler consists of a pair of jaw levers i), I) pivoted at their inner ends to eaeh other and to n .vhillletrec bar or equivalent part a by means oi a pivot bolt :1 passed through a pair of as need lugs (L2 projecting from said bar a. The outer ends of the jaw levers I) are curved in o'nosite directions l and when l)l'()tt, ,l1t together form a ring shaped mouth 0 adapted to engage a ring on the end of a (rare. or equivalent device. The intermediate portions of said lovers 1 are straight and between these straight portions and their pivoted inner extremities are oppositely projecting curved portions or loops 7) within which aspring c is arranged for :toroing the jaw levers apart.

On the upper taco ol' the straight portion of the lower jaw lever is an integral hook (Z formed in its outer edge with a notch (1 and in the corresponding portion of the upper jaw lever is formed a slot 6 to receive said hook (i when the mouth portions 5' oil. the jaw lovers are closed.

Fta'med in the upper jaw lever and extending longitiulinally ":o as to intersect the transverse slot 0 is a sl j" which serves as a guide for a sliding bolt adapted to enter the notch (.Z in the hook or lug (Z. The bolt 2' is pivoted between the outer ends of two links 9 arranged on opposite sides of the upper jaw lever and having their inner ends pivoted at 5 to the intermediate portions of the angular arms of a U shaped lever The ends oi the arms oli this lever /i are pivoted at h on opposite sides ot the upper jaw lever and said lever /L is of such shape that it is adapted to swing over the loop 71* of said in an easily roleasi upper jaw love and carry the pivots g inwardly past the longitudinal center of the pivots h, as shown in Fig. 3 of the drawings, and thereby lock the bolt 2' in its operative position within the notch (.Z of the hook (I. When the lever ii. is swung to its position shown in Fig. the bolt is retracted to re lease the hook or lug (Z and thereby permit the spring 0 to open the device. The meeting ends of the mouth portions or loops 6' of the jaw lovers are preferably made with a projection and recess 6 b, respectively, to engage one another for more effectively roupling the jaw levers when the device is closed.

\That i claim as my invention and desire to secure by Letters Patent of the United States t. A harness trace coupling comprising, in combination, two pivoted jaw levers having eurved ends shaped to form a ringshaped mouth when the device is closed, one of said jaws having a slot, a spring interposed between said jaw levers, a hook upon the other of said jaw levers adapted to enter said sl'ot. a longitudinally movable bolt in the slotted jaw lever to engage said hook, a U-shaped lever having its arms pivoted at their ends on opposite sides of said slotted jaw lever and links (connecting the intermediate portions of the arms of the U- shaped lever to said bolt, the pivots uniting the links to the arms of the U-shaped lever being adapted to pass the longitudinal plane ot the pivots of said arms of the lever, for the purpose set forth.

harness trace coupling comprising, in combination, two jaw levers pivoted together at their inner ends and having curved outer ends shaped to form a ringshaped mouth when the levers are brought together, the latter having straight intermediate portions, one ot which is formed with a transverse slot, the last. mentioned jaw lever being also formed with a longitudinal slot intersecting said transverse slot, a lug upon the intermediate portion of the other jaw lever and adapted to enter said transverse slot, said lug being formed with a notch to register with said longitudinal slot, a sliding bolt in said longitudinal slot, a spring interposed between said jaw levers, a U-shaped lever to straddle one of the jaw levers and neving its arms pivoted at their In witness wliereof I have signed this ends to said aw lever and links connecting specification in the presence of 'two Wit- 10 the intermediate portions of the arms of nesses.

said U-shaped lever to said sliding bolt, the GUSTAV GOLDBAGH pivots uniting the links to said U-shaped lever being adapted to pass the longitudinal Witnesses:

plane of the. fulcrum points of said lever, for PAUL SCHOENERSTOCK, the purpose set forth. ERNST KATZ.
